You are certainly correct about the future perf. periphrastic. It is in
the Morphology that Prof. Brooks and I wrote. I just failed to pick it up.

I am a bit troubled by the phrase "at a single point." I would emphasize a
completed action with a continuing result. Most of the time with the
perfect, either one or the other (complete action or continuing result) is
emphasized.
